concrete modeling in abaqusReinforced concrete is a complicated material to be modeled within finite element packages. A proper material model in finite element model should inevitably be capable of representing both elastic and plastic behavior of concrete in compression and tension. The complete compressive behavior should include both elastic and inelastic behavior of concrete including strain softening regimes. There are quite large numbers of numerical material models available to develop complete stress-strain curves of concrete for compression and tension like CDP(Concrete Damage Plasticity). However, these methods are not directly applicable with the input format required for the finite element packages like ABAQUS FE package.

Abaqus modeling steel structures beam columnsBeam element in the Abaqus element library was used to model the beams and columns. The selection of the type of element to be used is based on the fact that the investigation considers the global response of the frame in column removal scenario. For this purpose beam theory is sufficient. All beam elements in Abaqus are beam-column elements that mean they allow axial, bending, and torsional deformation. However, torsion is not applicable to in-plane behavior of the 2D frames. The beam properties are input by defining the cross-section from the predefined cross-section library. At each increment of the analysis the stress over the cross-section of beam elements is numerically integrated to define the beam.

Masonry modeling in abaqusModelling of masonry structures under static and dynamic loads compared with experimental studies has low cost, but must be considered that these models provide accurate results when the components and interactions between them and the forces applied to the modelling has done accurately.Masonry structures due to bed joints have anisotropic behaviour that shows orthotropic softness and strength characteristics which would depend on the interactions between materials.To analyze the masonry structures, micro and macro modelling methods are examined.In micro modelling all components and materials are modelled individually, while in macro modelling whole wall is modelled as a part including mortar, block and joints properties.

dam modeling in abaqus sluid structure interaction fsiOptimally designed structure generally saves large investments especially for a large structure. The size of hydraulic structures is usually huge and thus requires a huge investment. If the optimization techniques are employed in the design stage, the project investment can be effectively minimized.In the study of fluid-structure interaction, one of the main problems is identifying the hydrodynamic pressure applied to the dam body during an earthquake. three methods are used in solving the fluid-structure interaction problem through the use of the finite element method. These methods are: Westergard, Coupled Euler- Lagrangian (CEL) and Lagrange-Lagrange.

The mechanical behavior of structures that are in contact with soil is affected by the interaction between the soil and the structure (SSI). Some structures where SSI is especially important are buildings, bridges and oil rigs.There are numerous constitutive models that describe the inelastic behavior of soils, with the Mohr-Coulomb criterion being the simplest to implement. For a more accurate analysis, more advanced constitutive models should be used such as Cam-Clay, Drucker Prager but the Mohr-Coulomb criterion gives a good first approximation of the inelastic behavior. When modeling the soil as a continuum, the Mohr-Coulomb criterion is implemented in Abaqus/CAE

Abaqus modeling of soil improvement

 Soil improvement in its broadest sense is the alteration of any property of a soil to improve its engineering performance. This may be either a temporary process to permit the construction of a facility or may be a permanent measure to improve the performance of the completed facility. The result of an application of a technique may be increased strength, reduced compressibility, reduced permeability, or improved ground water condition.Different ground improvement methods can be used to prevent toe slope failure, such as geosynthetic reinforcement, soil nailing, ground anchors, micropiles, stone columns, retaining walls and ... All of them can be modelled in abaqus and be analysed.

Structural Analysis Blast modeling in Abaqus

Explosion Blast Analysis can be performed to ensure explosion safety for critical and hazardous surroundings. You can think of offshore, drilling platforms and military vehicles or vessels. The explosion will create a pressure wave which can cause huge damage to your structures. Another application of this Structural Analysis is a blast screen to absorb the pressure wave energy.Two ways is for modeling blast in abaqus,first pressure loading and second Conwep.Pressure loading due to an incident shock wave caused by an air explosion is calculated using the CONWEP model in Abaqus/Explicit.
